“…This has many benefits, including the ability to retrofit and eliminate the need for a cryogenic separator and shift reactor. In post-combustion, CO 2 is usually absorbed or desorbed using a solution containing alkanol amine [30][31][32].…”

In the last few decades, excessive greenhouse gas emissions into the atmosphere have led to significant climate change. Many approaches to reducing carbon dioxide (CO2) emissions into the atmosphere have been developed, with carbon capture and sequestration (CCS) techniques being identified as promising. Flue gas emissions that produce CO2 are currently being captured, sequestered, and used on a global scale. These techniques offer a viable way to encourage sustainability for the benefit of future generations. Finding ways to utilize flue gas emissions has received less attention from researchers in the past than CO2 capture and storage. Several problems also need to be resolved in the field of carbon capture and sequestration (CCS) technology, including those relating to cost, storage capacity, and reservoir durability. Also covered in this research is the current carbon capture and sequestration technology. This study proposes a sustainable approach combining CCS and methane production with CO2 as a feedstock, making CCS technology more practicable. By generating renewable energy, this approach provides several benefits, including the reduction of CO2 emissions and increased energy security. The conversion of CO2 into methane is a recommended practice because of the many benefits of methane, which make it potentially useful for reducing pollution and promoting sustainability.

Post-combustion CO2 capture using aqueous alkanolamine solutions has a great potential to reduce anthropogenic CO2 emissions but the large-scale deployment of this technique is hindered due to a highly energy-intensive solvent regeneration mainly because of poor CO2 desorption kinetics. To overcome this limitation, we synthesized a series of mesoporous HZSM-5 catalysts through facile alkaline desilication and surfactant-induced re-assembly of dissolved species originating from the parent HZSM-5 crystals, and evaluated their performance to optimize the CO2 desorption rate from benchmark 30 wt. % monoethanolamine (MEA) solution under mild temperature condition (40-82 oC). X-ray diffraction (XRD) patterns showed that the synthesized catalysts retained their crystallinity. Desilication by treatment in the alkaline medium led to a remarkable development of mesoporosity, with an increase in the Brunauer-Emmett-Teller (BET) surface area as well. The experimental results suggested that the synthesized catalysts significantly enhanced the CO2 desorption rate at low temperatures (up to 350-580% at ≤ 82 oC), improved the total amount of desorbed CO2 up to 60%, and minimized the heat duty by 24-37%. Detailed characterization revealed that the synergistic effect of higher mesoporosity and increased number of Lewis acid sites (LAS) and Brønsted acid sites (BAS) was crucial to improve the CO2 desorption rate. Based on the characterization and experimental results, a plausible reaction mechanism for catalyst aided CO2 desorption was also presented. This investigation highlights the role of catalysts in optimizing the CO2 capture process and presents new understanding for the design of highperformance catalysts for this purpose.
